Consider removing tests expecting 'sudo' from skip-list

Details

Description

Right now a test that validates iTest's functionality to elevate user privileges is set to be skipped

@Ignore("requires sudo")

the test actually works quite fine if password-less sudo is configured. And such configuration is a requirement for some other tests as well. Shall we consider making password-less sudo an official requirement for the tests and allow this test case?

Another option would be to change @Ignote to @Assume and make an explicit check for password-less sudo
